研究背景

功能:

Pore-forming subunit of a mechanosensitive non-specific cation channel. Generates currents characterized by a linear current-voltage relationship that are sensitive to ruthenium red and gadolinium. Plays a key role in epithelial cell adhesion by maintaining integrin activation through R-Ras recruitment to the ER, most probably in its activated state, and subsequent stimulation of calpain signaling. In the kidney, may contribute to the detection of intraluminal pressure changes and to urine flow sensing. Acts as shear-stress sensor that promotes endothelial cell organization and alignment in the direction of blood flow through calpain activation. Plays a key role in blood vessel formation and vascular structure in both development and adult physiology (By similarity).

Note: In erythrocytes, located in the plasma membrane (PubMed:22529292, PubMed:23479567). Accumulates at the leading apical lamellipodia of endothelial cells in response to shear stress (PubMed:25119035).

Application: IF/ICC    Species: Human    Sample:

FIGURE 1. mRNA and protein expression patterns of mechano-sensitive channels in human ureter. (A) Relative mRNA expression of mechano-sensitive channels in intact human proximal ureter or mucosa. Total RNA was extracted from intact proximal ureter or mucosa for RT-qPCR. The primer sets for amplification of the four channels are shown in Table 1. In view of the significantly lower expression of the four channels relative to beta-actin, mRNA expression in each case was determined relative to Piezo1, which showed the highest expression. Summary data are the average values of six experiments. Expression patterns were similar in intact ureter and mucosa. (B) Immunofluorescence labeling showing that TRPV2, TRPV4, Piezo1, and Piezo 2 are mainly expressed on the urothelium of ureter. Urothelial cells were marked with the specific urothelial marker AE1/AE3. The scale bar = 100 μm.
